Do you pay attention to what's being said over the in-store intercom while you're shopping in Pennsylvania Walmart stores?

If the answer is no, you'd better start.

The same voice you hear overhead, while you're cruising the aisles, telling you about special sales and when the store will be closing for the night, could also save your life, according to Common Cents Mom.

You may or may not know...I didn't...that Walmart has secret intercom codes. Codes that are meant to inform employees of certain situations so they know how to proceed and know what to do.

The article says there are four different types of codes that Pennsylvania Walmart stores use...colors, numbers, letters and word codes.

Several of the color codes you really need to be aware of for safety reasons.

Code White

Code White means there's been an accident, like an injury, that's occurred in the store.

Code Red

Code Red means there's a fire of some type in the store. Usually there's a number after Code Red indicated which aisle the fire is in.

The rest of the color codes are where you really need to pay attention. As soon as you hear them you need to get out of the store right away.

Code Brown

Code Brown means there is shooter in the store. When you hear this code carefully get out of the store as soon as you can or follow a store employee's instructions.
